Unable to send Teams adaptive card to office group members/security groups /DL groups. For single users it is working fine. But it is required to send to 1k+ users, if the loop is introduced I doubt that the flow will successfully run through the loop if it is more users.

Error in flow is "No user details with email or UPN 'SampleDistList@nandadev.onmicrosoft.com' were found in Graph."

Please refer below screenshot.
